Originality: 4.5 donuts. Haven't seen this done with ponies before, neither have I seen royal guards in Ponyville. Can't tell if lack of logic or potential for exciting backstory which divulges the secret lives of the royal guards gone vigilante. This is more likely than them being actual employees of Equestria's police force, that van does NOT look legit.

Vision: 3.5 donuts. Still lacking in pyrotechnics, plus STILL NO RARITY.

Technique: 4.5 donuts. Niiiice! This is the correct amount of background detailing without cramping Rainbow Dash's ego... I mean style. Would look better on Rarity.
